The Mysterious statues are large stone statues resembling a giant monkey head, created by the TokHaar with the Elder Kiln on the orders of the Elder Gods. As a creation of the kiln, they are considered to be part of the same Elder Artefact as the TokHaar and the kiln itself. There are 4 statues in total, and they are used during the Holy Grail quest to triangulate the entrance to the realm of the Fisher King, as Arthur's knights had turned them from their original directions they faced towards the grail. During the Seers' Village Task, players have to walk clockwise around the statue that is in Seers' Village to complete a task.
They are also used in the quest One of a Kind, where the player turns them to their original positions so they face towards the Submerged statue, which is referred to as 'The Sleeper'. Turning all four statues will reward players with 10,000 bonus experience.
